The symptoms of dizziness can occur when taking a hot bath: first of all, consider that the patient has insufficient blood supply to the brain. Taking a bath consumes part of the body’s energy, plus the water temperature rises, which can lead to the opening of the microcirculation of the skin and the expansion of blood vessels and cause the phenomenon of insufficient blood supply to the brain, causing dizziness. Secondly, hypoglycemia can also lead to dizziness, the body does not have sufficient energy when bathing on an empty stomach, patients are prone to hypoglycemia, the brain does not have reserves of glycogen, therefore, when the blood sugar level in the blood is reduced, the brain energy metabolism is impaired, causing dizziness caused by hypoglycemia symptoms. It is recommended to always take more warm sugar water orally before bathing, which can avoid the occurrence of insufficient blood supply to the brain as well as hypoglycemia.
